There has been a lot of talk about the Android operating system, and what will be the upgrade to it. Most Android devices that are newer (less than two years old) have already received their upgrade to Android M (also known as version 6.0 or Marshmallow) already, but eventually, version 7.0 (also known as Nougat or Android N) will also be available. This is the latest news on Android M Version 6.0 Marshmallow and Android Nougat Release Date for Sony Xperia Z5, Z4, Z3, and Z2 on Sprint, AT&T, US Cellular, T-Mobile, and Verizon.
So, what happened to Sony? They were a little slow when it came out with the rollout, as they have been in the past. There is a report on Tech Radar saying that most of the flagship family that includes the Xperia Z5, the Xperia Z5 Compact, the Xperia Z5 Premium, Xperia Z4 Tablet, Xperia Z3, Xperia Z3 Compact, Xperia Z2 Tablet, and the Xperia Z2 are all seeing the Android 6 Marshmallow upgrade.
In addition to those flagships, there is a report from Gear and Style Cheat Sheet that other products such as the Xperia M4 Aqua, Xperia C5 Ultra, Xperia C4, and the Xperia M5 will be getting the upgrade as well. Unfortunately, it won't be receiving the Xperia Z1 and the Xperia Z1 Compact.
Of those devices, the newer ones, which include that Z5 family of flagships have received their upgrade, but news is not clear as far as what carriers have received them and when. Normally, you can find all kinds of charts saying what devices has received what, but this doesn't appear to be the case for the Japanese company.
So what will be the first Sony devices to receive Android N? Chances are, it will be the Sony Xperia X devices first. Then it will be the Z5-branded, with the Z4 tablet, and the Z3 series. Given that the newer Android devices receive the upgrade first, it will probably happen in that order. Sort of like how the Z1 series won't be getting Marshmallow.
If you are a Sony user of a newer device in the United States, see if you can't get the OTA (Over The Air) download of Android Marshmallow now. Just go into the "Settings" and "System Update" to see if the upgrade is available. The upgrade may not be available depending on your carrier like T-Mobile, Sprint, US Cellular, AT&T, and Verizon. Feel free to leave a comment here saying whether or not you received your Marshmallow on your Sony device, as well as what carrier that you subscribe to.
